Letter from [G L] Brown, the Physiological Society, National Institute for Medical Research, Hampstead, London NW3, to [Henry] Barcroft, Physiological Laboratory, Queen's University, Belfast Is afraid that 'Switzerland is off as far as any more invitations are concerned'. Has had an invitation from Trevan but could not accept as he will be in Sweden by that time. Points out that the rumour about the adrenaline paper 'was started by...an incompetent referee' and hopes he has not worried himself about it. 2 July 1946
